Purpose
This study aimed to explore the feasibility and efficacy of percutaneous fixation
of minimally displaced scaphoid waist fractures using a 3-dimensional-printed guide
in 10 cases.
Methods
Fractures were examined using preoperative computed tomography. The skin interface
and bone models were reconstructed using computed tomography data. Guidewire insertion
was assisted by a guide. Computed tomography was performed 4–6 weeks after surgery
until healing of the fracture was confirmed. The mean follow-up period was 7 months
(range, 6–9 months). The fracture healing time, grip strength, flexion-extension arc,
patient-rated wrist evaluation, and Mayo wrist score were recorded.
Results
A total of 6 hands were in the dominant limb. The mean operation time was 41 minutes
(range, 32–70 minutes). Three (30%) scaphoids healed at 6 weeks after surgery, 8 (80%)
scaphoids healed at 8 weeks after surgery, and 100% scaphoids healed at 12 weeks after
surgery. After correcting for hand dominance, the mean grip strength was 84% (range,
71% to 95%) of that of the contralateral side. The flexion-extension arc was 97% (range,
82% to 100%) of that of the contralateral side. The mean Mayo wrist score was 95 (range,
85–100), and pain decreased to minimal levels. All patients returned to their preinjury
activities.
Conclusions
Three-dimensional printing is an effective and feasible technology that can help guide
intraoperative processes.
